Equine Infectious Anaemia (EIA)
On 13 March 3019, the North Carolina Department of Agriculture and Consumer Services reported one case of EIA in a mule in Transylvania County, NC. The animal displayed clinical signs and was euthanased. At post-mortem histopathological changes consistent for EIA were found. Additional blood from the animal was not available for testing for EIA, so out of an abundance of caution the case is considered presumptive positive by animal regulatory health officials. The remaining equids at the facility were tested and were negative for EIA and will be observed and retested in 60 days. Quarantine measures are in place.
Equine Herpes Virus-1 (EHV-1)
